Reverse filtering for deblurring

Python code implementing five reverse filtering (or defiltering) schemes for noisy image deblurring described in the following paper.

Dependencies

The code depends on a few common Python libraries (NumPy, ...). Install them via pip and the provided requirements.txt file. For example

$ python -m venv bbdeblur_venv
$ ./bbdeblur_venv/Scripts/activate
$ pip install -r requirements.txt

How to run?

One possibility is to execute the scripts in the sub-directory src

$ cd src
$ python test_color.py

Another possibility is to use the Python notebook, provided in the sub-directory notebooks. The notebook works on Google Colab (with the default installation).

Notes

See also the original (and more complete) MATLAB implementation in this repo.
